-so, l

Beit known that I, CYRUS B. MORSE, of Rhinebeek, in the county of Dutchess, and State of New York, have invented new and useful Improvements in Rails for Ring-Spinning; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable those skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification,` in which- Figure 1 represents a front view of a section of rails for ring-spinning.

Figure 2 is a cross-section of the rails, lthrough the lifting-rail support in the line :n fr, iig. 1, showing my improved tubular lifting-rod support.

Figure 3 is a top view of a. portion of the lifting-rail, showing my improved ring-holder.

Figure 4 is a horizontal section through the bolster-rails, in the line g/ y, fig. 2, showing the arrangement of my improved adjustable ring-rails.

Similar letters of reference indicate corresponding parts.

This invention relates to new and useful improvements in the construction of rails fory ring-spinning, and their connected parts, which consist, first, in a tubular support for the lifting-rod; secondly, in a device for adjusting thelifting-rail, by means of set-screws moving the position of the lifting-rod in or out, above or below, in transverse slots in the bolster and step-rails.

A represents the bottom or step-railof a ringspinning frame,f the bolster-rail, and C the lifting-rail. The lifting-rods D D have hitherto been set in bushings in the step and bolster-rails, without the means of adjustment, and they have been subjected to uneven wear at the two points above and below, in passing through each rail, giving a taper form in consequence ofthe irregular friction lproduced by the .varying motion of the liftingrod at different stages of winding the yar-.n on the cop. 'lhis defect in the wear of the lifting-rods at two points has caused much diiiieulty in the operation ci' ring-spinning.

To remedy the defect, I have constructed a tuhulnrlii'ting-rod support, E, split longitudinally into two equal parts a a, extending from the bolster to the step-rail, within which tube the lifting-rod is itted exactly, as is a piston, so that the surface has an equal bearing the whole length of its movement, and this wears evenly from top to bottom, and never gets out ot' true, as shown clearly in iig. Q. The tubular lifting-rod support E is held in place by two set-screws b Z, on opposite sides of euch rail, which screws hear against the sides of the ends l placed in transverse slots in the rails, as shown in figs. 2 und 4. By means of these screws, the lifting-rail can be adjusted lprecisely as it may require, from time to time, in consequence of displacement out of line by the drawing pressure of the piilley-bclts towards the cylinders of the spindles. Instead of' the ordinary method of securing the rings c c in the liftingfrail with side screws, I place them in holders (l (Z, which are screwed upon the ruil, and arranged so us to be adjust-able i'or centring the ring perfectly with the spindles. The holder d is a ring-band, within which the ring e is set. On opposite sides are two lugs er enrse e, which are slotted with slots it', tig. 3, wider than the tightening-screws z, which pass through them to fasten the ring-holder firmly to the top ot' the rail. By means of these slots in the cnrs ofithe ring-holder, the ring-holder can be adjusted on .the rail iniany direction by the screws, so as to centre the ring exactly upon the spindle. To do this is the work of a moment only, hy means of a eentring-bloclc slipped over the spindle, and setting the ring true around it, before screwing up the ring-holder fast upon the rail.' V

Having described my invention, I claim as new, and desire to secure by Letters Patent-- The tubular lifting-rod support E, in combination with the slotted bolster and step-rails A B, and with the lifting-rail C, for the purpose of adjusting said lifting-rail to and frompthe centre of the machine, substantially as herein set forth.
